Thousands already present at the anti-BNP protest due to kick-off soon. However, the police have been quite aggressive. A number of individuals spotted at the Bush protest have been arrested. More to come later.

Update: It has turned into a really lively event with thousands thronging the streets. The police are taking pictures of the protesters but the DJ simply advised the crowd to "stick your middle figure up to that camera right there". Pictures and video footage will come soon.

Well, that was better than I thought it would be. Initially the turnout didn't look great, but it seems to have picked up once we got started. Lots of trade union banners, gay pride people, Muslims, a very mixed crowd and precisely the kind of microcosm of London that one would have hoped for. Whatever pressure was coming from the police at the start seems to have died down as it got underway, unless I missed something. I had to leave before the speeches and performances at the end, so anyone who stayed on can fill me in. Anyway, here's your first batch of pics. The protest started at Tooley Street near the GLA building and marched to Trafalgar Square, with music, speeches and performances going on throughout.
